I'm encountering a similar problem with methods. In my case, I'm
passing 6 arguments to the method Simple:
Simple("/var/adm","messages","root","root","0640","14")
action=cf.simple
server=localhost
returnvars=alpha
returnclasses=null
The method is pretty simple for testing purposes:
groups:
doit = ( any )
control:
MethodName = ( Simple )
MethodParameters = ( dir file owner group mode age )
actionsequence = ( shellcommands )
shellcommands:
"/bin/echo vars: $(dir) $(file) $(owner) $(group) $(mode) $(age)"
files:
$(dir)/$(file) owner=$(owner) group=$(group) mode=$(mode)
action=touch
alerts:
doit::
"Testing received vars: ${dir} ${file} ${owner} ${group} ${mode}
${age}"
ReturnVariables( ${dir} ${file} ${owner} ${group} ${mode} ${age}"
)
ReturnClasses( success )
When cfagent is evoked, parsing of cf.simple fails with the following
errors:
cfengine::Simple: cf:cfengine::/var/cfengine/modules/cf.simple:19: Invalid mode
string ($(mode))
cfengine::Simple: cfengine::/var/cfengine/modules/cf.simple:19: Warning: mode
string is incomplete
If I comment out the files section, the file is parsed successfully and
everything works as expected. Likewise, I can include the same files
section in cfagent.conf with $(mode) defined in control and cfagent.conf
will parse successfully. Alternatively, I can define $(mode) in
cf.simple's control block and the file will parse successfully.
However, in the last case I don't get the value I passed to the method
for that variable.
shellcommands does what you would expect and echo's the values to all 6
variables. All of the variables are returned to the calling process.
Any ideas on what's going on? :-)
Thanks,
